Detective Guardrail

Governance control that identifies noncompliant resources after creation and reports or remediates them.

Definition

Detective guardrails continuously evaluate configurations, using tools such as AWS Config rules, Azure Policy audit effects and Security Command Center findings. They complement preventive controls by catching drift and violations that preventive policies cannot block.

Example

An AWS Config rule flags any security group allowing 0.0.0.0/0 on port 22.

Exam tip

If a question says 'identify' or 'alert on' noncompliant resources, think detective controls such as AWS Config.
